Abstract :
This paper presents a novel stabilization method for eliminating oscillation in RF CMOS nonlinear power amplifiers. By system identification technique, large signal stability information comes out. Then a band-stop feedback network is introduced in the first stage of power amplifier designed for 802.11b application. This two-stage power amplifier implemented with UMC 0.18 um CMOS technology is stabilized by this novel method without the cost of other performance degradation.
